Total impedance in primary side of transformer
Consider an ideal transformer with load connected (simple ideal case for simplicity). So I learnt about reflected impedance Z2'=a²Z2 (in terms of secondary impedance reflected on the primary). My ...

Solving for equivalent resistance and flow of current
Equivalent resistance between terminal A & N is 2.44 \$\Omega\$ (answer key). Instinctively I tried to find it by assuming 4\$\Omega\$, (5+6)\$\Omega\$, (10+5)\$\Omega\$ were in parallel as they ...

Kirchoff's Voltage Law in this mesh
I found the following results using nodal analysis and confirmed them via mesh analysis: The voltage across the 2\$\Omega\$ resistor is -4\$\text{V}\$. \$I_3 = 3\,\text{A}\$ and \$I_2 = -2\,\text{A}\$...
